[SOLVED] Windows VM in Proxmox 8.3.0 is unable to get an IP address

[CheeseRat007]

I am running a Proxmox Cluster in a nested Hyper-V environment. After the installation I login and create a Windows VM and assign "vmbr0" as the Network device. But inside the VM I am unable to get an IP address.

The Proxmox is connected to the network and is able to access the internet(checked via pinging google.com), while the same Linux Bridge when connected to the VM is unable to get an IP.

What should I do get the network access?

For you to answer this what details should be attached.

auto lo
iface lo inet loopback
iface eth0 inet manual

auto vmbr0
iface vmbr0 inet static
address 10.131.1.XX/16
gateway 10.131.0.1
bridge-ports eth0
bridge-stp off
bridge-fd 0
#FE

source /etc/network/interfaces.d/*

Thank you so much for your question!! I spent half a day beating my head against the monitor trying to solve this. Then I saw the word 'promiscuous', and it immediately clicked. Here, it fixed everything immediately:

UPD: BTW, you also might want to change the adapter to trunk mode:

Set-VMNetworkAdapterVlan –VMName my_pve_vm_name –Trunk –AllowedVlanIdList 10-100 –NativeVlanId 0
